Nozzle

Munstycke 5

The invention relates to a nozzle for adjusting the air flow to a room.

The following publications are known in the art: SE-9100975, SE-7402503, NO-169406 and SE-970031.

10

A nozzle structure is known from the disclosure, wherein the regulating member comprises a circular cross-sectional inlet air port associated with a duct that narrows in the direction of airflow and terminates in a guide designed to direct the airflow obliquely or parallel to the ceiling surface into the room.

This application discloses a completely new type of nozzle construction comprising a body having a circular cross-section with a flap-shaped guide member inserted therein. The guide portion divides the space of the annular body having an inner circular section into two channels; channels A 1 and A 2. The curved oh-20 divider provides an air flow that can be smoothly directed sideways from the nozzle structure.

«

The end of the second duct section A2 also has a cover section which contributes to the lateral orientation of the air flow.

It is also possible within the scope of the invention to provide a nozzle structure in which the guide member is formed of two metal plates having different temperature coefficients. In this case, the air flow direction can be adjusted according to the temperature.

1.1 1 Can be used as a wall or ceiling.

The nozzle according to the invention is characterized in what is stated in the claims.

Fig. 2 is a separate view of the angry associated guide part.

As shown in Fig. 1A, the nozzle 10 comprises a nozzle body portion 12 having a circular cross-section and a flap-faced cover portion 13 extending in front of the nozzle which engages the annular body member 12. Inside the annular body member 12, tj is divided by a guide portion 14 into channels A 1 and A 2, whereby a flow of air can be directed to channel A 1 as well as channel A2, respectively. The guide portion 14 is a flapper structure which is · · · V curved The tongue-like airflow guide portion 14 thus separates the channels A1, A2 within the annular body portion 12. The end edge 140 of the guide member 14 extends to the level of the cover member 13 and the function of the guide member 14 is to smoothly control the flow from both the channel A 1 and the channel.

Figure IB is a partial sectional view of the structure of Figure IA. As shown in Fig. 1B, the inside of the annular and circular cross-section body 12 is divided into channels A1 and A2, which channels are divided by a tongue-shaped guide portion 14 having a curved surface 14 ', 14 ".

Figure 1C is a sectional view I-I in Figure IA. As shown in Fig. 1C, the flow Lj in channel A 1 is directed obliquely to the axis X by the curved underside surface 14 'of the guide portion 14 and the air flow Lj in channel A2 on the other side of the guide portion 14 passes and is directed in the same direction with respect to the central axis X of the structure 15. The direction of flow 1 ^ is also influenced by the cover portion 13 at the outlet of channel A2.

Fig. 1D shows the attachment of the part 10 to the nozzle hole 16 of the body R so that the snap-acting resilient fastening parts 15, which are a kind of claw-like parts, will be located on the rear surface R 1 of the plate R. is located between the annular rim 12a of the body portion 12 ii · of the end portion of the fastener 15. Part 15 each allows the nozzle 10 to be rotated about its central axis X to control the direction of air flow.

Figure 2 shows the guide portion 14 in a separate view. The guide member 14 is preferably also made of a plastic material, such as the entire nozzle assembly 10. However, it is possible to carry out an embodiment of the invention wherein the guide member 14 is made of metal sheets having different thermal quality coefficients. are superimposed and their different coefficients of temperature ·· ·: V lead to a temperature-deflection position of the control member 14. This allows the position of the controller 14 to be adjustable so that the direction of the airflow 30 L always adjusts to the temperature.

The guide portion 14 may also be constructed of memory metal. In this way, the direction of the air flow, which is controlled by the temperature, is also obtained. The operation of the guide portion 14 is similar. The nozzles can be assembled into a larger unit to form a complete air distribution device whose air distribution properties can be changed as desired by adjusting the individual nozzles. One embodiment could also be that the height position of the guide portion 14 may be varied relative to the body 12 of the nozzle 10 and to the plane of the retaining plate R. In this case, the air jets Lj and Ij can also be adjusted. In this embodiment, the guide member 14 can be positioned in e.g. grooves inside the body 12 which act as clamps for the guide member 14.
